Southern Sudan, 2008:

Nya’s family has now returned to their village. Visitors in a jeep arrive and talk to the village chief about water. Nya is confused by what there is to discuss about water. 

Southern Sudan, 1985:

Salva’s group must now cross the Akobo desert, which they think will take three days. Salva’s shoes have been worn through and he must go barefoot. He stubs his toe on a rock and his toenail comes off. He starts to cry and give up, but his uncle urges him to continue. He asks Salva to just walk a little bit further and this is how Salva is able to continue. The next day they come across a group of men lying in the desert. Some have died but others are still alive. Even though they desperately need the water for themselves, some of Salva’s group gives water to the collapsed men.
